Anyways, Each car was hand built to the buyers order instructions. (At some rediculous cost back in the late 70s and early 80s. The company went out of busniess sometime in the late 80s early 90, but the dyes and molds were sold to a startup company that restores and builds new ones today. They did use a Caddy, Lincoln or Chevy engine for it's powertran and Gm subframes, but the body was the creation of Brook. The first models were smaller and ran with big block GM engines, built for SPEED!!!.This model has a small block engine in it and was at the mercy of the government for emissions control, so the high performance engines were no longer installed. Very disappointing.
